Hi, I’m Marcel! I work on #NLP for lesser-resourced languages, multilingual NLP, cross-lingual transfer, tokenisation, and trying to keep up with the flood of LLM-related research. Joining Bluesky seems like a good opportunity for a new & shiny #introduction, so here goes!

Every time.
I was having an emotion, and I hate that.

Every time.
I often long for a place to just post whimsical personal updates for friends, but that kind of place doesn’t exist anymore. In my personal bubble, social media has long become too fragmented and/or abandoned for that purpose.

Just found out that yet another paper on North African Arabizi didn't find our work worth citing. they even wrote "No Arabizi-specific metric or resource exists for our dialect selection ». We were the first to release an annotated dataset for this dialect, published at acl and shit. Discouraging.
![Your dataset looks very cool, but I don't understand why you say “no Arabizi-specific metric or resource exists for our dialect selection”? When you contacted me, it seemed to me that you were aware of my work on Arabizi (e.g., [1,2], not to mention the cross-lingual work with Maltese [2] or character-based language models for Arabizi [4]). One of the crucial points of this work was also to propose translations into French from Algerian Arabizi, which could have helped you use a ground truth for your translation models. I'll be honest with you, I find it extremely discouraging to see that pioneering work in the processing of a language with such limited resources as Algerian Arabic dialect is not cited, even though it has been published in the major conference in the field and the data is freely available (unlike the vast majority of dialectal resources for Arabic). If even colleagues working on the same language don't find it necessary to cite us, what's the point of investing so much time and money in this type of work?
In short, I hope your work doesn't encounter the same pitfalls.

I'm conducting research on how ACL's peer review policies impact NLP research quality, career trajectories, and inclusivity within our community. I am running a survey, which would take around 7-10 mins to complete: forms.cloud.microsoft/e/j2jr9nH3X0
I would really appreciate insights from y'all!

Why does every social media feed eventually end up looking like:
[outrageous thing happening in the US]
[extremely polarizing AI take]
[random semi-funny meme]
[shocking thing happened to person I don't know]
[yet another reason climate change is worse than we thought]
It's so emotionally tiring.

Idk who needs to hear this, but you do *not* need to glaze the reviewers of your papers when you respond to their feedback.
Be grateful, sure, but don't wax poetic about how insightful and magical their farts are.

German is infamous for its compound words, but one of my personal favorites that amazes me every time is "Haltewunschtaste", the button that you push on a bus or tram to indicate you want to get off, a.k.a. the "stopping wish button".
